description
This device contains six independent 2-input
NAND drivers. It performs the Boolean functions
Y = A
B or Y = A + B in positive logic.
The center-pin configuration reduces lead inductance when compared to the
′
AS804B. The reduced lead
inductance minimizes noise generated onto either the V
CC
or GND bus. This reduction is significant in
high-current switching applications.
The SN74AS1804 is characterized for operation from 0
°
C to 70
°
C.
